COLLAPSIBLE COPYHOLDER FOR TYPEWRITERS.

Application iiled July 16,

To all lwhom it may concern:

Be it known that I, JOHN L. JoNEs, a citizen of the United` States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certainnew and useful Improvements in Collapsible Copyholders for Typewriters, of which the following is a specification.

This invention relates to new and useful improvements in copy-holders fory typewriters, and more particularly to a collapsible copy-holder which may be readily attached to, and removed fro-m, any standard typewriter. n

It is the principalobject o-f my invention to provide a copy-ho-lder which may be easily and firmly secured to a typewriter `to support the copy in such a position that it may be plainly visible to the operator.

It is a further object 0f the invention to provide such a copyholder with means for readily collapsing` it upon the machine so that it need not be removed from the latter when it is turned under the movable top 0f a typewriter desk of the disappearing type.

Other important and incidental objects will be brought out in the following specification, and particularly set forth in the subjoined claims. i

In the accompanying drawings illustrating one form of embodiment of my invention, Figure 1 is a right side-elevational View of my copy-holder attached to a typewriter.V Figure 2 is a similar view of the same in its folded or collapsed position. Figure Y8 is a top plan view of the means for clamping'the copy-holder to the typewriter. Figure 4 is a front view, partly in section, of the copy-holder. -Figure 5 is a plan view-of the top of the saine. Figure 6 is a left side-elevational view thereof. And Figure 7 is a side elevational view of the means forl opening the copy advancing rolls.

u Throughout the specificationandv drawings, similar reference characters denote corresponding parts. j Y

Referring to the accompanying drawings illustrating my invention, the numerals 1, 1 designate two right-angled clamping members. In the rear end of one of these members there is provided a longitudinal slot 2 into which there freely projects a guiding lug '3 from the 'corresponding end of the other member. Projecting through a hole in the latter, and through the slot 2 in the 1923. sriai No. 651,738.

first member 1, is the threaded end of a bolt Just behind the curved portions7, 7 of the v,

members 1, 1, there projects through the latter a transverse rod 10. On one end of this rod there is a head 11 which bears against the outer surface of one clamping member, the other end of said rod being threaded to receive a :wing nut 12 which may be turned against the outer surface of the other clamping member to draw the curved4 portions 7, 7 of both of them tightly against the legs 8, 8 of the typewriter frame. Thereare also secured to the' clamping members 1, 1 just behind their curvedy portionsv 7 ,4 7 angle pieces 13, 18 through which there-d 10 also passes and which are adapted to engage the back surfaces of the rear legs of the typewriter when the wing nut 12 is tightened, to assist the curved portions of the clamping members in firmly gripping them. After the front ends of the clampino members 1, 1 are firmly attached to the Iegs of the typewriter frame, the wing nut`6 is tightened to firmly `connect the rear ends of those clamping members to make them a solid support for the collapsible copy-holder now to be described. I

j Firmly secured to the rear inner parts of the forwardly .projecting portions of the clamping members 1, 1, are two. upright supporting members 14, 14. Pivotally secured to the upper end of each one of these supporting members, by a screw 15 or other suitable threaded element, is an arm 16. These arms may be firmly held in any of their adjusted positions by wing nuts 17 on the outer ends of the pivot screws 15. (See Figures 1 and 2.)

The arms 16, 16 terminate at their upper ends in short horizontal portions 18,18. Secured upon the top of each horizontal porltion 18 is a forwardly projecting, elongated bearing member 19. Each bearing member 19 comprises a metal block which, in its rear end, contains a transverse hole `to receive one end of a roller spindle 20. In front of this holethe bearing member is cut away to leave` a front flange 21 between which and the rear portion of said member, one end of a roller spindle 22 is free to travel.

The front face of the rear portion of each bearing member 19 is concaved to receive the roller spindle 22, the latter being maintained in said concaved face by a concaved slide 23 from whichV there projects forwardly, through a hole in the flange 21, a pin 24 that is surrounded between the flange andthe slide by a hel-ical Compression spring 25. To the top of the bearing member there i'sapplied a cover plate 26 which holds ithe spindle 22 andthe slide 23 within it during their travel. (See Figures: 5 and 6.)

Mounted on the -spindles -20 and 22 are rubber rollers 27 27 which are adapted to receive between them -a copy sheet (not shown) for the use of the operator. The roller 22 is` drawn away from the roller 2O against the compression of the spring 25, by vthe following means-to insert or remove a copy sheet. Loosely projecting through holes in the arms 16, 16 below thebearing members 19, 19,"is a rod 28. The latter also passes through an upright metal piece 29 that is secured at its lower end to a boss 30 which projects inwardly from the lower portion of theright arm 16. (See Figure 4.)

' Tightly secured to the rod 28 between'the right arm 16 and themetal piece 29, is an arm 31 whose top end is conca-ved to fit the roller spindle 22. A similar yarm 32 isffiX- edly attached to the rod 28 near the left supporting larm 16. FiXedly secured to the eXtreme right end ofthe rod 28 is an operating lever 33 which, Vwhen depressed by the operator, will move the roller spindle 22 outwardly against the compression springs 25, 25 to'prov-ide between therollers 27, 27 =a Space of sufiicient width to easily receive the copy sheet, which is `advanced by the means now to be described.

Fixedly secured to the outer end of the roller spindle 20 above the ylever 33, is a ratchet disc 34 which is adapted to be engaged by a pawl 35 pivotally secured by a pin 36`1to one end of a lever 37. Attached to the pawl-carrying Aend of the latter is a spring 38 which is adapted to press against therear end of the pawl to maintain its nose port-ion in engagement with the teeth of the ratchet disc. Pivotally secured to the other end of the lever 37 is the horizontal end of a verticalr'od 39 which is pivotally secured at its lower end, by a pin 40,to the Vupper end of a vertical rod 41. The latter passes downwardly'through an eye-piece 42 secured to the arm 16, being connected at its lower end by a pin 43 to one end of a bell-crank lever 44 that is pivotally secured by a pin 45 to the rear part of the forwardly projecting portion of the right clamping member 1. (See Figures 1 and 2.)

The lower end of the bell-crank lever '44 is connected by a link 46 to the upper end of anotherbell-crank lever 47 which is pivotally secured by a pin 48 to the lower end of a vertical supporting piece 49 that depends from the right clamping member 1. The lower end of the bell-crank lever 47 is connected by a link 50 to the rear end of a horizontal lever 51 which is pivotally secured by a screw 52 to theV front end of a curved angle member 53th-at depends from the frontend of' the right clamping member 1. (See Figures 1 yand Pivotallysecured by a. screw 54 to the front end ofthe lever 51, is an'operating lever55whicl1 carries'on` itsfront end a button 56 foreng'agementby a finger on the operators hand. The rear end of thelever 55 isnotche'd, as itt/57, to engage-a screw 58 on theA outer end of the lever 51to'ma-ke the latter and the lever 55fone continuous lever foractuation by the operator to turn the rollers 27, -27`through the ratchet mechanism, levers and links just described. (Sec Figures 1 and 2.)

Projecting rearwardly from the lower part ofthe-supporting element 53 is an eyelet arm 59 through which there projects downwardly, a threaded pin'6'0 havingfa knurledhead 61. The lower end ofi this pin ism the path of upward movement of the rea-r end of the lever 51, so that the number of' spaces the rollers 27 are turned when the lever 55 is depressed, maybe controlled by adjusting the height 'of the pin 60.

After each depression vof the lever 55, it

will be returned to its normalposition by ya helical spring 62 connected between the front end of the lever 37 and the right larm 16. (See Figure 1.) This spring not only returns the lever 55 t0 its normal position through the levers and links hereinbefore described, but vit also draws the pawl 35 counterclockwise over the teeth of the'ratchyet disc 34 to a point where its noseportion will engage the disc'to turn itthe desired number of spaces'whenthe lever 55 is again l depressed by the operator.

Firm'ly .secured to the righty bearing member 19, are the ends ofV two rods 63, '63 which project upwardly and then'horizontally over the rollers 27, 27 respectively, through holes ina bracket 'piece "64 on the left bearing member 19, to act as top guides for the Vcopy sheet which passes between the rollers. The guide rods 63, 63 pass loosely through the bracket piece 64, and the ends'of t-he roller spindles 2O and 22 pass'freely through'the leftbea'ring member 19, sopthat the arms 16, 16 may be easily spread apart or moved toward each other when the clamping mem- *bers 1, 1y are being appliedto 'dierent Width typewriters. (See Figures 1 and 2.)

In operation, whenit is desired tovinsert a vcopy ysheet'betweenlthe rollers 27 27 the lever 33 is depressed'by a 'buttoir65 whichfit carries on its front end, to the position shown in dotted lines in Figure 7, for the purpose of withdrawing the front roller 27 a suiiicient distance from the rear one to permit the insertion of the copy sheet between them. Then, when the pressure of the linger is released from the lever 33, the springs 25, 25 will force the roller spindle 22 inwardly ,to carry the front roller into a suiiiciently firm contact with the copy sheet and rear roller, that when the latter is turned by the ratchetmechanism, it will advance the copy sheet the desired distance. As stated before, this distance will be determined by the position of the stop pin 60 which limits the upward movement of the rear end of the lever 51 to which the lever 55 is pivotally connected.

l/Vhen it is desired to collapse the copyholder so that it may be carried into a desk by its movable support without interfering with the stationary parts of the desk, the wing nuts 17, 17 are loosened t0 permit the arms 16, 16 to be turned toward the outer end of the lever 55 until the bearing members 19, 19 engage the top of the machine, as shown in Figure 2. The outer end of the lever is then turned about its pivot screw 54, toward the arms 16, 16, as is also shown in Figure 2. The typewriter is now free to be carried into a desk by its movable support, without fear of the copy-holder interfering with its inward movement. Further more, when the copyholder is .removed from the typewriter, it may be collapsed as above described for storage in a small space, or Jfor the purpose of being easily carried from place to place.

Having described my invention, I claim:

1. A copyholder for typewriters, comprising a pair of clamping members for attach- .ing from the other end of said lever to a point near the point ofconnection between the adjacent arm and its supporting member, and means depressible near thertypewriter keys, connected to the lower end of said rod for the purpose specified.

2. A copy-holder for typewriters, comprising a pair of clamping members 'for attachment to a typewriter and to each other, upright support-ing members secured to the clamping members, arms pivotally secured to the upright supporting members, a pair of feed rollers supported by the upper ends of said arms, a ratchet for turning said rollers, a lever, a pawl carried by one end of said lever to actuate said ratchet, a rod depending from the other end of said lever to a point near the point of connection between the adjacent arm and its supporting member, a horizontal, jointed operatmg lever, and linkage connected between the inner end ot said collapsible lever having a pressure end near the typewriter keys and the lower end of the depending rod, the latter and said arms adapted to be turned toward the outer end of the jointed operating lever, which is also adapted to be moved toward them to collapse the copy-holder.

In testimony whereof I have hereunto set my hand this 14th day of July, 1923.
